Subject: [PATCH] Remove tun/tap from the default device rules
|
||||
|
||||
Looking through git blame, this was added by commit 9fac18329
|
||||
aka "Initial commit of runc binary", most probably by mistake.
|
||||
|
||||
Obviously, a container should not have access to tun/tap device, unless
|
||||
it is explicitly specified in configuration.
|
||||
|
||||
Now, removing this might create a compatibility issue, but I see no
|
||||
other choice.
|
||||
|
||||
Aside from the obvious misconfiguration, this should also fix the
|
||||
annoying

> Apr 26 03:46:56 foo.bar systemd[1]: Couldn't stat device /dev/char/10:200: No such file or directory
|
||||
|
||||
messages from systemd on every container start, when runc uses systemd
|
||||
cgroup driver, and the system runs an old (< v240) version of systemd
|
||||
(the message was presumably eliminated by [1]).
